PHILIP R. ROSENBERG AND RALPH HERMAN, OF BALTIMORE, MARYLAND.

ADVERTISING LAMP.

Application filed July 29, 1922. Serial No. 578,386.

To all whom it may concern:

Be it known that we, PHILIP R. ROSEN- BERG and RALPH HERMAN, citizens of the United States, residing at Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Advertising Lamps, of which the following is a specification.

This invention relates to improvements in advertising lamps, and has for its object to provide a simple, cheap and attractive device for all.kinds of advertising, and has especial reference to advertising on a revolving shade or dome.

The invention consists of the novel construction and arrangement hereinafter more fully set forth in the following specifications and pointed out in detail in the appended claim.

In the accompanying drawings,--- 7 Figure 1 is an elevation of a lamp having our invention applied thereto.

Figure 2 is a top plan view, on an enlarged scale, of the vane disk.

Figure 3 is an enlarged vertical longitudinal section of the vane disk and shade, the latter being broken away, showing the position of the lamp and pintle point.

Figure 4 is a detail view of the glass bushing upon which the vane disk rests.

Figure 5 is a side elevation of the wire frame which fits around the bulb, and the pintle point upon which the vane disk revolves.

Figure 6 is a top plan view of Figure 5.

Referring to the accompanying drawing, forming part of this specification. and in which like reference numerals designate like parts throughout the several views thereof, 1 designates a stand having an electric switch 2. and an electric bulb 3. Secured to the bulb 3, is a wire frame 4. formed of a pair of side portions and a coiled bottom portion, the, latter is extended around the socket of the bulb and with the coils thereof arranged in superposed relation. The upper end of one side portion of the frame is bent around the tip of the bulb and then extended upwardly to form a pintle, and the upper end of the other side portion of the frame is bent to engage that side portion provided with the pintle 5, whereby the side flange 8 of the vane disk 9 rests. The said vane-disk 9 is provided with a number of vanes 10 and a downwardly-projecting flange 11 on its outer edge. Secured to the said flange 11 is a depending shade 12 having a metal band 13 on its lower end. The said shade 12 may be transparent or semitransparent, and the advertising is printed, painted or otherwise secured to the outer surface of the shade so that it will be readily seen when the light is on inside the shade.

The heat from the electric light within the shade will be thrown up against the vanes 10 of the vane-disk 9 causing the latter, andconsequently the shade 12, to revolve. thus bring the advertising matter on the shade. into view as the shade is revolved. The bushing 6 being made of glass will permit the shade-to revolve with but very little heat as the friction between the pintle point 5 and the bushing 6 is reduced to a minimum.

Having thus described our invention, what we claim is:

An advertising lamp comprising an electric bulb, supporting means therefor, a wire frame formed of a pair of side portions and a coiled bottom portion, said bottom portion extended around the socket of the bulb and having the coils thereof arranged in superposed relation, the upper end of one of said portions connected to'the upper terminal portion of the other of said portions and the said upper terminal portion bent around the tip of the bulb and extended upwardly to provide a pintle, a flanged bushing fitted over and supported by said pintle, a disk provided with a series of vanes and further having a flange mounted on the flange of the bushing, and a shade depending from said disk.

In testimony whereof we affix our signatures.

PHILIP R. ROSENBERG. RALPH HERMAN.
